Our daily lives are filled with a wide variety of electromagnetic waves . To ensure that radio products are safe to use, they must undergo RF exposure evaluation. RF exposure evaluation, EMF measurements, or SAR testing can be used to conduct this evaluation. Time-consuming SAR measurement methods are used by the SAR standard. Mobile wireless device compliance test lead times are incompatible with industry needs and are becoming a significant pain as 5G communications proliferate. When it comes to peak spatialaverage SAR evaluation, this study proposes a new technology aimed to solve this challenge and provide instantaneous and accurate peak SAR evaluation.
